Precision 7740 TIM's

Hi everyone,

I have a Dell Precision 7740 with a NVidia Quadro 5000 in it and I am trying to have it repasted and padded. I have the Thermal Grizzly Kryonaut for the paste, and was thinking of Fujipoly for the pads. The problem I am encountering is that nowhere online is it posted the dimensions of the thermal pads for the computer. I have looked in the user manual and called tech support, but have been unable to find anything anywhere. I looked up the heatsink, and all I could find were pictures. Based on what I could see, there seem to be different sized pads and different colors. Does anyone happen to know what thicknesses are present for the heatsink and what the different colors mean?
